JULIUS C. RIE'IH AND JOHN H. CHAMBERLAIN, OF CHICAGO, ILLINOIS.

PNEUMATIC GRAIN-MOVING APPARATUS.

Specification of Letters Patent.

Patented June 26, 1906.

To all whom it may cen/cern:

Be it known that we, JULIUs C. RIETH and J oHN H. CHAMBERLAIN, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Pneumatic Grain-Moving Apparatus, of which the following is a specification.

This invention relates to improvements in an apparatus for moving rain by pneumatic means, and more particularl to that class adapted Jfor unloading cars an7 boats.

The principal object of our invention is to provide a pneumatic grain-moving apparatus and to construct the same in such a manner that in its operation'the` grain will not be broken or shattered.

Another object of this invention is to provide a vacuum-chamber, having integral therewith a dumping means consistin of a series of slides so operated as to a ways maintain a vacuum in the chamber, and thus render the apparatus operative at all/times.

Wvith these objects in-view and such others as may hereinafter appear our invention consists in the particular construction of the various parts and in the novel manner of combination and arrangement of said arts, all of which ill be more fully describe and s ecically pointed out in the appended c aims.

In the drawings forming a part of this specification, Figure 1 is a vertical sectional view. Fi 2 is a sectional view. taken on line A A, ig. 1. Fig. 3 is a perspective view of one of the slides and diaphragme.

Referring by numerals to the drawings, 1 represents a vacuum-chamber having in the top thereof an air-outlet 2, adapte to be connected to an air-pump. Mounted in the wall oi the chamber is a grain-intake pipe 3,

one end oi which, 4, is adapted to ,be connected to a pipe or hose (not shown) which extends into a granary car or boat, as .the case maybe. The other end of the pipe 3 is enlarged, as shown at 5, and is curved downward, so as to throw the grain against.

the rubber cushion or pad 6, arranged within the chamber o posite the intake-pipe. The grain is also de' ected against said ad by the deilector 7, arranged just'above t e intakepipe. Mounted upon one side of the chute is a casting 10, having a journal 11 therein for" the reception oi a shaft 12 and two .correspending arms 13, pivotedto which are corresponding lever-arms 14, having slots 15,

which receive pins 16 inone end ot the slides 17, the said slides restingu on rollers 18 in a transverse position in the c ute beneath diaphragms 19, which are provided with substantially diamond-,shape openin s 2,0, designed to prevent the crushingoft je grain in the operation ofthe slides. Pi' voted tothe lever-arms 14 byone end are', couplings 21, the other ends of which are connected to anlar-shaped slides 22, mounted upon the ee ends of the arms 13. These angularshaped slides are in enga centric wheel 23, mounte upon the shaft 12, which is driven by a pulley-wheel 24, adaptedto be connected to any suitable power. The bottom of the chute is provided with an air-tight door 25 and oppositel -disposed ipe connections 26, thus provifiin means or depositing the grain at the en of the chute or for conveying it farther, as may be desired. Assuming that a pump is attached to the pipe 2 and that the grain-intake pipe is connected with a granary, upon the pump bein set in operation a partial vacuum is produce inthe vacuum-chamber, whereby the grain is caused to rush in through the pipe 3, which is gradually enlarged and so curved as to deiiect the grain against the rubber ad, thereby reducing the'force with Whic lit would naturally enter if the pi e was not enlarged at its depositingend andt owin the grainwith less force against the pad. he grain `after striking the pad falls to the bottom of the chamber, where it rests upon the upper slide until said slide is drawn out by the lever-arms operated by the eccentric Wheel, the slides being so arran ed and operated that when one slide is in 1lille other is out. Thus when the up r slide is drawn out the grain drops ement with an ec-vv e througli the chute to the bottom slide, and

IOO

Having thus described the various features..

of enr invention, what we claim asnew, and

desire to secure by Letters Patent, is

1. In a pneumatic grain-moving ap ara- IIO tus,avac'uumchamber, havin inlet an outlet pipe connection, the i et-pipe being gradually enlarged toward its discharge end and curved downwardly, a rubber cushion within the chamber opposite the inlet-pipe;l

gradually enlarged toward its discharge en a deeetor arranged Within the chamber above the inlet-pipe, a rubber cushion opposite the discharge end of the inlet-pipe, a chute communicating with the bottom of the chamber, diaphragms having substantially diamond-shaped openings, arranged transverse within the chute, transverse slides mounted upon rollers beneath the diaphraginsl-`leverarms o erated by an eccentric wheel 'for alternate y opening and closing the slides, substantially as speeied.

3. in a pneumatic grain-moving apparatus, a vacuum-chamber, having an air-outlet in the top, an inlet-pipe in the Wall of 'the 'chamber,y the inlet-ipe being gradually enlarging'toward its 'soharging end7 the discharing end of the inlet-pipe projecting into the c iamber and curved downward, a deiiector in the chamber arranged above the inletpipe, a rubber Cushion in the chamber arranged opposite the inlet-pipe, a Cb ute communicating with the bottom of the chamber, transverse diaphragme having substantially diamond-shaped openings therein arranged Within the chute, transverse slides mounted upon rollers beneath the diaphragms, leverarms connected to the slides and o erated by the eccentric Wheel for alternate y moving said slides in and out, means for o eri-ing or Closing the bottom of the ohute, an ipes communicating with the bottom of the c ute, substantially as s ecied.
